A drysuit should be a snug fit with room for insulation undergarments under it so you can still move freely when you’re wearing it. You should not experience too much restriction on movement with layering under the drysuit, as this would indicate the drysuit is too tight. But if there is no resistance to movement, the drysuit may not be tight enough.
The scuba diving basics include mastering your buoyancy control and mastering your air consumption to extend your dive time and have fun diving.
You can set most drysuit exhaust valves to vent air automatically while underwater, but to do so the air in your drysuit needs to migrate to where the exhaust valve is located on the suit. You can adjust the valve and how much air is released, but it’s best to have the valve set to fully open.
You could wear a wetsuit under a drysuit, but it’s not the best way to keep you warm. So you should wear an under-suit that’s designed for wearing under a drysuit, which is designed to keep you warm instead.
For your own safety when diving in a drysuit you should leave your drysuit valve open, but close it a quarter turn from fully open to avoid any leaks. An open drysuit valve will then automatically vent if you ascend to let out the expanded air from your drysuit.
It’s best to use your drysuit and not your BCD for buoyancy when diving in a drysuit, as it’s better to use only one air cell for buoyancy to have only one to vent on your ascent. If you use your BCD for buoyancy you’ll need to use both, as you’ll have to add air to your drysuit to avoid drysuit squeeze.
When you are diving in a drysuit you still need a BCD to attach your scuba tank to your back and for buoyancy when you first enter the water.
You can scuba dive when it’s raining if the rain isn’t part of a storm with strong winds that’s causing the sea state to be dangerous to dive and if the visibility hasn’t been badly affected above and below the water. If the rain is part of a storm and the winds are too much for diving you can’t dive.
You can swim with whale sharks in the Galapagos Islands and the best time to go is from July to November. The best way to see whale sharks is from on a Galapagos scuba diving liveaboard on a trip to Wolf and Darwin Islands. Most Galapagos whale sharks are huge and some measuring up to 12 metres.
50 logged dives is recommended to scuba dive the Galapagos Islands. Most Galapagos scuba diving liveaboards have a minimum of 50 logged dives and PADI Advanced Open Water certification, as the conditions can be challenging due currents and surges, ocean swells, water temperatures and deep dives.
It’s possible that at certain times of the year great white sharks could be near to the Galapagos Islands. This is because of the water temperature drops to within a great white shark’s “temperature comfort zone” of 12-24°C (54-75°F) in June to December and sealions are present as a food source too.
Pros And Cons Of Nitrox Diving: The top pros of Nitrox diving are improved diver safety and extended bottom times. Whereas the worst cons include depth limits and extra cost of diving.
